Perfect for intended use
Your review: Purchased this to have consolidated storage for guitars and bass guitars in their cases. Also purchased an additional 4 shelves to accommodate the 8 instruments and cases. Use is in a designated "music room" in my house. Didn't need the weight rating, but the specific size being available was deciding factor.
Pros: Easy to assemble; the posts are all numbered from the bottom up and are light enough that they don't stand out after assembled. No tools were required, although a concrete floor helped to set the adjustable feet into the bottom of each post.
Cons: Need good lighting when assembling, the numbers are very faint, but the plus of making assembly so easy far outweighs any issues.
